Probably too large; 0.004 Gm. or 1/15 grain is said to have produced death in a person enfeebled by chronic bronchitis.
From 0.001 Gm. to 0.002 Gm., or 1/60 to 1/30 grain, repeated once an hour or once in two hours, is safer. Emetic, by mouth (hypodermic administration is better), 0.01 Gm. or 1/6 grain (U.S.P.).

This may be repeated at ten-minute intervals until effective, but it should be remembered that in some cases apomorphin produces toxic effects without causing vomiting.
